The most changing fields will be I think:
Status (read/unread): in fact I'm affraid of this at most - any
mail incoming to the system will need to be
indexed at least twice
This is why I recommended you to use a filter created from your
database for use in queries that require read/unread clauses, rather
than reindexing your documents. As the read/unread flag is updated you
just update the filter and don't touch the index more than looking up
what document number a specific email is represented by in the index.
Using a filter will also have the side effect of making your queries a
lot speedier compared to a TermQuery.
